IMPROVEMENT IN HYDRANTS.

To all whom it may concern Be it known that I, GEORGE C. BAILEY, of the city of Pittsburg, in thecounty of Allegheny, and State of Pennsylvania, have invented a new and useful Improvement'in-Hydrants; andl do herebyde clare the following to be'a full, clea'r, and exact de-' scription thereof', reibrencebeing hadto the accompanying drawing, making a part of this specification, e

which shows a vertical sectional view of my improved valve. The natureof my invention consists in an improved construction of a hydrant or other like valve.

To enable others skilled in the art to make and use e my invention, I will proceedl ,-todescribe its construction and mode of operation.

The disk-valve a, of the usualor anyknown construction, is screwed on to or otherwise attached to the lower end ofthe discharge-pipe or plunger l).

Its lower face has packing c, which lits neatly on to the seat c.

Apertures Q are made in the valve a, through which, when the valve c is'raised from its seat c', the water passes'fromthc supply-pipe d, upward through thedischarge-pipe b,- and out at the spout above.

Surrounding the valve a, and valve-seat, c', which latter forms a part of it, isa valve-chamber, j, madeslightlybell-mouthed, as at f, so as, when putting it in place, the more easily to be' guided on to the upper end of the supply-pipe (l, on to which it is screwed, a

` p aeking-ring or gasket, e, being interposed between t 1e two.

VThe valve-chamber j' extends up above the upper face ofthe valve a, a sutiicient distance,.so that a collar, or annular' ring, ,bored to the exact size of the.

pipe b, maybe slipped thereon above the valve a., and

screwed into the upper end of the chamber j, leaving suiiicient room` forthe play of the valve.

Through this collar i, a small waste-hole, i,is made.

vBetween this collar 'i and the valve a, and resting on the upperface of the valve, is an annular packingring, o, ot' India rubber, or other suitable material, which movesonly with the valve.

When the valve' is raised, and connnunicationis packing-ring ol comesaga'inst .the lower end ofthe waste-passage#` and closes it.

When the valve is seated, 'and the outow of water is stopped, the waste i is uncovered, and the water in the discharge-pipe or plunger l) escapes.

It is often necessary or desirableto remove the valvechamber and valve for repairs, cleaning, 87o.

. To ldo this easily, I attach to the plunger-pipe b, a

radially-projecting lug, s, and make a vertically,-v projecting lug s', on the upper en'd vof' the cha-m,- berj, in such relative adjustment, that as the plunger b is turned or rotated, one lug' will engage the other, and so theturning of the pipe b as a wrench, will screw the chamber j' on or oi the supply-pipe (l at the joint d', as may be desired; but for the purpose of removing or putt-ing in place the. valve-chamber, I do not .limit myself to the use of thel lugs s s,'since other equivalent device for locking or interlocking the two, such as a crab-clutch, key, or feather, may be substituted therefor.

The eollar'i may, if' so desired, be cast with the valvcchamber as a part thereof, in which case the lower part of the valve-chamber, containing the valve-seat, may screw on-and off. so as to admit of' the insertion of the valve.

Noris it necessary that the valve-seat be cast as a- The valve a, it will be observed, in a hydrant constrncted as described, always shuts against the pressure of the water.

What I, claim as my invention, and desire to secure by Letters Patent, is-

I. The lng's, attached to or forming part of the hollow plunger and discharge-pipe, in `combination with the removable valve-chamber j, having a corresponding lug, s', all arranged and combined substantially as set forth.

. 2. The discharge-pipe b, lugs s s', valve-chamberf, and joint d', when combined in the manner substantially as shown and described.

3. yA`hydrant-valve seat inserted in Vor forming part of'a removable valve-chamber, and a vertically-mov- .ing plunger or discharge-pipe, in combination with a locking-.device constructed and operated substantially as described.

4. The discharge-pipe I), valve a, movable annular `packiiig-ring o, and waste-passage i', when combined opened from the supply to the discharge-pipes, the

as shown.

In testimony whereof, I, the said GEORGE C. BAI- LEY, have hereunto set my hand.
